A wire 308 connects one of the members ofthe reversing switch 83 and the electric motor 40, and awire 309 connects the other member-of the reversing switch 83 and-said electric motor 40.

The washing .machine when not in use is in folded position as indicated in Fig. 5, the bumper heads 188 and 196 and the bumper foot 205 bearing respectively against the rear wall 281 and the curved portion 286 of the front wall 285 of the wash tub 279, to maintain the platform 20 in a vertical plane.

To locate the washing machine in operative position, it is pulled up by grasping the handle 90 of the cover 72, until the bifurcated locking heel 227 of the locking pawl 225 locks with the locking heel 206 of the inclined member 200, see Figs. 1, 2, 3 and 9. It will be noted that at this time the separator plate 242 is positioned between the bearing face 153b of the lug 153 and the bearing face 185a of the lug 185.

The springs 221 with their bands 220 assist in unfolding the washing machine.

The clothes to be washed, the soap and the water or other fluid are located in the 'wash tub 279. The switch 83 is now positioned to locate the appurtenances of the motor for rotation in l one direction or the opposite thereto. Next the switch 82 is positioned to start the electric motor 40. With the rotations of the armature shaft 42 of the electric motor v40, the worm shaft 43 with the worm 46 is turned and thereby the worm wheel 54 is turned. The rotations ofthe shaft 51 of the worm wheel revolves the arm 57, which oscillates the link- 60 and the arm 59. Thereby the oscillating cross shaft 58 is oscillated. By

this means the stems 115 with their suction plung`v ers having the shells 130 are reciprocated and beat the clothing in the wash tub 279. A partial vacuum is made between the plungers and the clothing when the plungers rise. The openings 137 and 149 in the head 135 break the said vacuum when the plungers are spaced from the fluid in the Wash tub, which allows the clothing to drop,

Which further agitates said clothing and circulates the water through them. The annular space 141 between the lower portion of each suc tion plunger having the shell 130 and its head 135, prevents the water in the wash tub 279 splashing upwardly. If there is excessive pressure against the lower heads 135, the springs 127 will be compressed and cause the suction plungers having -the shells 130 to move upwardly and relieve the pressure.

Referring particularly'to Fig. l, the oscillating beam 95 is oscillated by the oscillating cross shaft 58, through the intervention of the supporting collar 65, the flat side faces 66 coacting with the vertical opening l97 in'the hub vportion 9 6 of the upper oscillating beam 95. If an abundance of material to be washed is in the wash tub 279, the lower oscillating .beamv 99, is positioned with the opening 100 of the hub portion 101 in contact with vthe flat side faces 66 of the collar of the oscillating shaft 58, and the opening 97 of the hub portion 96 is in contact with the guide pin 80. After the clothing has been beaten by the suction plungers 130 the water is drawn from the wash tub, the electric motor 40 Y is stopped, the oscillating beams 95 and 99 with their suction plungers having the shells 130 are removed, and the clothes wringer 250 is' placed in operative position, by means of the supporting pins 265 and the spacer pin 263. The locking sleeve 270 is placed in position to connect the shaft 256 and the shaft 51.

The motor 40 is again started to lturn the rollers 254 and 255 of the clothes wringer 250.

After the clothing has been Wrung, the clothes wringer isdisconnected. The machine is now again folded in the Wash tub 279. This is accomplished by first swinging up the separator plate 242 in the direction of the arrow A, Fig. 3. The operator next slightly tilts the washing machine toward the rear wall281 of the wash tub 279 by grasping the handle 90 and the pins 168 are moved toward the bearing face 229 of the locking pawl 225 until the ball 172 is engaged with the locking groove 170, and the locking heel 227 is disengaged from the locking heel 206. The operator by controlling the handle 90 allows the machine to swing down on the journal pins 215, the locking heel 227 sliding on the rib 20la until the bearing face 153a of the lug 153 bears on vention and the present exemplication is to be www.'
